Existing solutions use only 2 telephone antennas in the roof antenna, and two additional antennas, e.g. in the bumper, are used as the 3rd and 4th antenna. The disadvantages: additional cabling, additional installation space, additional antennas.
For this reason, fuba takes a different approach. The antenna is explicitly used as a functional design element: the integration of all antennas in a single, distinctive and highly visible component.
